摘要:
A system for increasing component longevity in a display device includes: a display device; a sensor for detecting an audience associated with the display device; and a control subsystem connected to the sensor. The control subsystem is configured to deactivate at least one component of the display device when no audience is detected by the sensor. A method of increasing component longevity includes determining the presence or absence of an audience with respect to a display device; and deactivating at least one component of the display device when the audience associated with the display device is not present.

A method of testing a coating on a reflector having a first focal point includes placing a mirror at the first focal point of the reflector and angled to orient with an area on the coating. Electromagnetic (EM) radiation is directed to the mirror which then directs the EM radiation on the area. The EM radiation which is reflected from the coating is collected onto a sensor disposed at a second focal point. The intensity of the EM radiation collected on the sensor is detected.

One embodiment of an optical medium includes a substrate, a data recording layer positioned on the substrate, a selectively transmissive layer positioned on the data recording layer, and a label recording layer positioned on the selectively transmissive layer, the label recording layer optically accessible at only certain wavelengths through the data recording layer and through the selectively transmissive layer.

A cool light source includes a reflector having a band-reject reflective coating and an underlying absorptive coating. The cool light source also includes a window with a band-pass transmission function that is substantially complimentary to the band-reject reflective coating.

A infrared (IR) light absorbing reflector is formed with a substrate that supports a first IR absorptive multilayer part having multiple layers of partial IR absorbing thin films. The first IR absorptive multi-layer part supports a second visible light reflecting multilayer part.
